Mck SembWever commented on CASSANDRA-2388:
------------------------------------------

For the use-case above it will solve restricting to the correct datacenter, but the sorting will still be based on proximity to the wrong node?

> ColumnFamilyRecordReader only tries the first location for a given split. We should try multiple locations for a given split.
